The factory NSX magneto-rheological (MR) shock absorbers are known to prematurely fail. Symptoms include reduced or completely eliminated damping effect (the car pogos or has an extremely harsh ride) which can result in very poor handling and poor ride comfort. When the shocks are inspected, shock fluid can be seen on the shaft and covering the shock absorber and surrounding suspension components.
After observing these failures, ScienceofSpeed sent a factory shock absorber to AST x Moton Suspension in the Netherlands, a high-end motorsports shock absorber manufacturer, for inspection to understand the problem. It was determined that the accelerated wear was caused by the stiff top mount increasing side load on the relatively short internal shock shaft top guide. The premature wear of the top guide allows axial play of the shock shaft, resulting in failure of internal seals
ScienceofSpeed has developed a plug-and-play replacement for the factory shock absorber with our partner AST x Moton. The MR design is replaced with AST's high-quality, motorsports-grade monotube shock absorber, which is compatible with the stiff factory top mount, spring, and other factory shock absorber accessories.
Aside from a more durable design, the AST shock absorbers offer significantly improved motion control, even compared to a good-condition factory shock absorber. Aside from improved suspension performance, the high-speed damping tuned to the factory springs results in a smoother ride, eliminating the chassis shake experienced with factory shock absorbers when driving over uneven pavement.
The kit includes everything you need to replace your failing factory shock absorbers, including a tool set developed by ScienceofSpeed to disassemble the factory shock absorber so that the components can be transfered to the new shock absorbers.
The AST shock absorbers outperform the factory shocks in ride quality, motion control performance, durability, and adjustability, and are now also available for less than half the price of the factory assemblies.
Features
- Plug-and-play replacement for factory shock absorbers: this not only saves cost, but also keeps the factory features in place for comfort and durability.
- Addresses issue with failing factory shock absorbers: the shock absorbers are designed properly for the factory top mount and the weight of the vehicle addressing the issue that causes the factory shock absorbers to fail.
- Quality motorsports-grade shock absorbers: the AST monotube shock absorber is a motorsports-quality product that uses the same technology as the GT3 NSX, which also eliminates the MR shock absorber.
- Superior ride quality: due to the advanced AST design and the shocks being tuned specifically to the factory springs, motion control - especially high speed compression - is improved over the factory shock. The harshness from the factory suspension, felt during sudden suspension movement, such as with breaks in pavement, is eliminated. This not only improves suspension performance but also improves ride quality.
- Adjustable ride height: set the ride height to the factory position, or lower the vehicle by 10 or 20mm, by setting the spring perch to one of three positions. No lower springs or lowering kits are required (or recommended).
- Adjustable damping settings: the shock absorbers include adjustment knobs. Set the shock absorbers to our recommended settings and forget them, or tune the shocks to your individual taste.
- Compatible with factory electronics: cancellation modules are included that eliminate diagnostic codes from removing the factory shock absorbers. ScienceofSpeed has even sourced the factory connectors so that these are 100% "plug-and-play".
- Reduced weight: the weight is reduced by 1.4 lbs per front shock absorber and 1.0 lbs per rear shock absorber.
